avoided in the process. The information upon which the recommendations in this circular are based is derived from many sources
and may be taken to represent, in very condensed form the substance of the best spraying knowledge and practice to date, concerning the pests mentioned. Improvements and new discoveries are
being made, however, and it is likely that the recommendations for
1910 may need to be modified in time to come.

lessons in the way of regular yields and good profits from sprayed
orchards and irregular yields and no profits from unsprayed orchards, the fact still remains that many owners of fruit trees do
